3 Claims. (Cl. '1283'50) This invention relates to means for retainingsurgical devices such as a drainage tube, catheter, or the like inposition on the body of a patient.

It is often necessary .to leave such devices as nephrostomy or othertype drainage tubes or catheters in place particularly when a splintingcatheter or a drainage catheter having a Pezzar or Malecot head is used.Many arrangements have been improvised in an attempt to anchor suchdevices. Adhesive straps and bandage have been used and at times thecatheter has even been sutured to the skin of the patent. Nevertheless,a patent may, on moving, displace the catheter so that it becomescompletely removed from the wound. This has necessitated a secondoperation with reopening of the wound to replace the catheter.

It is, therefore, a principal object of this invention to provide aretention disk which may be readily removably aflixed to the body of apatent and which serves to removably anchor in the desired location onthe body of a patient surgical devices such as drainage tubes orcatheters or the like.

Further objects as well as advantages of the present invention will beapparent from the following description of a preferred embodimentthereof and the accompanying drawing in which Figure 1 is a rearelevational view of a retention disk constructed in accordance with thepresent invention;

Figure 2 is a cross-sectional view through the line 2-2 of Figure '1;

Figure 3 is a fragmentary view similar to Figure 2 showing the deviceinflated;

Figure 4 is a cross-sectional view through the line 4-4 of Figure 2;

Figure 5 is a cross-sectional view through the line 5-5 of Figure 3; and

Figure 6 is an elevational view partially diagrammatic showing theretention disk affixed to the body of a patient and anchoring a catheterin place.

Referring now to the drawing in detail, retention disk 10 comprises agenerally flat, soft, pliable disk portion 11, which may be annular asshown, having an aperture 12 which communicates with the bore 13 of atube 14 joined with disk portion 11 and projecting from the rearwardsurface thereof. Tube 14 branches adjacent to its rearward end to forman inflating tube 15 the rearward end portion of which may have asomewhat increased diameter to facilitate insertion of a plug 16. Aresilient sleeve 17 having a substantially thinner wall thickness thanthe wall of tube 14 is sealed in an airtight manner adjacent to its endsto the inner wall of tube 14. The intermediate portion of sleeve 17which is free and not secured directly to tube 14 forms an annular sacktherewith which communicates through passageway 18 with the bore 19 ofinflating tube 15.

Plug 16, which closes the end of tube 15, is formed of resilientmaterial such as rubber which closes on itself after having been piercedby and following withdrawal of an inflating instrument. The inflatablesack formed by sleeve 17 is conveniently inflated with a suitable fluid,such as water or air, by forcing a needle aflixed to a syringe throughplug 16. As shown in Figures 3 and 5,.sack 17a inflates to form twoannularly spaced protuberances which engage and retain a memberextending in the bore of tube 14.

Retention disk 10 is conveniently formed of rubber latex, suitablethicknesses in the shapes desired being' built up as is well known inthe art. Because of the manner in which rubber latex members may bereadily united so as to be virtually integral one with the other, thefinished product, for all practical purposes presents a continuous,integral surface which is readily maintained sterile.

Referring now to Figure 6, the forward end of the surgical device whichis to be retained to disk 10, such as catheter 21, is passed through thebore of tube 14 and introduced into the body cavity. The forwardlypresented surface of disk portion 11 is coated with a suitable adhesiveand the retention disk is moved along the tube of catheter 21 until itis snug against the skin of the patient. The disk readily conforms tothe contours of the patients body. The inflating fluid is thenintroduced into sack 17a which distends to engage but not close thecatheter tube. The adhesive may be any suitable surgical skin adhesivebut preferably is one which does not have any deleterious effect uponeither the skin of the patient or upon the material of which the disk ismade. It should be readily removable without leaving any obectionableresidue.

The terms and expressions which have been employed are used as terms ofdescription and not of limitation, and there is no intention in the useof such terms and expres sions of excluding any equivalents of thefeatures shown and described or portions thereof, but it is recognizedthat various modifications are possible within the scope of theinvention claimed.

What is claimed is:

l. A surgical retaining device, comprising a disk adapted to conform toand to be anchored to a portion of the body of a patient, a tube joinedwith and extending from one surface of said disk, said tube having abore oommunicating through an opening formed in said disk with theopposite side thereof, a resilient member secured to a portion of theinner surface of said tube and having a free portion intermediate theends thereof forming a chamber with said tube, and means for inflatingsaid chamber to distend said free portion of said resilient member intothe bore of said tube and thereby anchor a surgical device such as acatheter extending through said tube bore.

2. A surgical retaining device, comprising a disk having an apertureformed therethrough, a first tube joined with and extending from onesurface of said disk with its bore in registration with said aperture,said disk being adapted to conform to and to be adhesively removablyanchored to the body of a patient with said aperture and bore inregistration with an opening into the patients body, a distendablemember which is more readily distendable than said first tube, saiddistendable member extending within said first tube and having its edgeportions sealed to said first tube so as to form an airtight enclosuretherewith, and an inflating tube having a bore communicating through thewall of said first tube with the interior of said enclosure, whereby asurgical device such as a catheter or the like extending through thebore of said tube into the body opening of the patient is anchored inplace when said enclosure is inflated and thereby distended to engagesaid device.

3. A surgical retaining device, comprising a disk hav- 3 ing an apertureformed therethrough, a first tube joined with and extending from onesurface of said disk with its bore in registration with said aperture,said disk being adapted to conform to and to be adlumively removablyanchored to the body of a patient with said aperture and bore inregistration with an opening into the patients body, a second tubeformed of resilient material which is more readily 'distendable thansaid first tube, said second tube extending within said first tube andhaving its end portions sealed to said first tube so as to form anairtight enclosure therewith, and an inflating tube having a borecommunicating through the wall of said first tube with the interior ofsaid enclosure, whereby a surgical device such as a catheter or the likeextending through the bore of said tube into the body opening of thepatient is anchored in place when said enclosure is inflated and therebydistended to engage said device.
